Comment (by Imprevisible):

 Based on that:[https://datatracker.ietf.org/doc/html/draft-pantos-http-
 live-streaming-20#section-3.4](https://datatracker.ietf.org/doc/html
 /draft-pantos-http-live-streaming-20#section-3.4)
 I can't use a lot of codecs:
 {{{
 Supported Packed Audio formats are AAC with ADTS
    framing [ISO_13818_7]; MP3 [ISO_13818_3]; AC-3 [AC_3]; and Enhanced
    AC-3 [AC_3].
 }}}

 As I can see on the apple website, FLAC is also possible. But I don't see
 the SPF of each one of them. For information, this ffmpeg command is
 generated with a python script, to select the right audio index, the right
 parameters.
